Windows
only: Free media file converter FormatFactory is a handy all-in-one
utility for taking one kind of audio, video, or picture file and
converting it to another. The interface is a dead-simple drag-and-drop
affair, and it's meant for running batches of files through
converters—FLVs to Windows Media, MPEGs to iPod-friendly video, DVDs to
DivX files, etc. You won't get a lot of options for quality control,
compression rate, or other tweaks, but for some folks, that's really a
benefit. FormatFactory is a free download for Windows systems only.
